Filed: 1990-01-30
Abstract: PURPOSE:To attain lots of reserved operations with the few number of switches by adopting the constitution such that plural kinds of reserved operation modes are independently implemented by using a mode changeover switch, a time division setting switch, a display section and a reservation operation switch respectively and the reservation is cancelled. CONSTITUTION:When a specific reservation operation mode is desired to be executed, at first a mode changeover switch 10 is used to select the relevant reservation operation mode and when the display of a display section 30 reaches an object reserved operation mode display, the reserved time is set by using an hour/minute switch 20 for the reservation setting. When the setting is finished, a mode changeover switch 10 selects sequentially the remaining reserved operation mode to decide whether the reservation is set or cancelled. In the case of cancelling the reserved operation, an hour switch 21 is used to match an hour indication with a cancel mark 101 and a minute switch 22 is used to match a minute indication with a cancel mark 102. When the reserved time of each reservation operation mode is set, a reserved operation switch 40 is closed to start the actual reserved operation as to the preset reservation mode.

Title: Facsimile equipment
Inventor: YOSHIDA SEIICHIRO
IPC: H04N1/32
Filed: 1989-01-30
Abstract: PURPOSE:To make repeatedly executed transmission operation by an operator in a transmission side unnecessary by storing the picture information of an original, which can not be transmitted, and the telephone number of a transmission destination to a memory, calling the telephone number of the transmission side, which is informed by a sound signal, from a reception side and transmitting the picture information stored in the memory. CONSTITUTION:When the operator designates a one-touch key or an abbreviated dial number, a network control part 2 calls the designated telephone number in a telephone number memory 1 for the prescribed number of times. In such a case, when a facsimile equipment in the reception side is occupied, the set original is read by a reading part 3 and read data are encoded by an encoding part 4 and stored to a picture signal memory 5. When the storage is finished, the network control part 2 calls the telephone number to a telephone set exclusive for telephone call, which is registered in the telephone number memory 1, in the reception side. Then, when it is detected that a calling partner picks a receiver up, a switch 10 is changed over to a sound synthesization part 6 side. Thus, it is not necessary for the operator in the transmission side to repeatedly execute the transmission operation and the other original can be transmitted.

Title: Temperature monitoring for electrically energized conductor
Inventor: NUMAJIRI FUMIYA
IPC: H01H37/32
Filed: 1986-02-04
Abstract: PURPOSE:To monitor a temperature of an electrically energized conductor accurately, by sticking a part of a plate-like shape memory alloy on the surface of an electrically energized conductor to sense changes in the shape caused at critical temperatures intrinsic to the shape memory alloy. CONSTITUTION:The figure (a) shows a side section of a shape memory alloy at a normal temperature. A sheet-like shape memory alloy 2 is stuck with an adhesive on the surface of an electrically energized conductor 1 of a power equipment, power transmission bus or the like. Here, the stuck part 3 is located bias to one end side of the shape memory alloy 2 and the area thereof is more than half of that of the shape memory alloy 2. A portion where this shape memory alloy 2 is not stuck serves as a deformation part 4 at the shape return action. Now when the electrically energized conductor 1 generates a heat, the heat is transmitted to the shape memory alloy 2 through the stuck part 3 when the temperature of the alloy 2 exceed the intrinsic critical temperature, as shown by the figure (b), a shape return action takes place to deform the deformation part 4. This deformation enables the detection of abnormal heat generation state.

Title: Phase comparator
Inventor: TANAKA MASATO
IPC: H03K5/26
Filed: 1982-02-15
Abstract: PURPOSE:To avoid the increase of settling time due to the variance of phase comparison output, by expanding a comparable region after detecting the possibility that the phase of a comparing pulse gets close to an unstable point from the preceding comparison output. CONSTITUTION:The output of a counter 1 is fed with data to a D type flip-flop circuit 3 of (m-1) bits. At the same time, a servo pulse T formed based on a control pulse reproduced from a magnetic tape is supplied through a clock input terminal. Then the output of the counter 1 is fetched to the circuit 3 with the supply timing of the pulse T. In this case, a clock enable state is obtained when both outputs Q1 and Q2 of the counter 1 are set at 0 or 1, and the Q1 is fetched to a flip-flop 6. When the Q1 and Q2 are set at 0 and 1 respectively, they are not replaced and held. As a result, the phase comparison output is expanded by a gate 5 and the flip-flop 6.
